<P>PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of obtaining a sufficient fuel consumption improving effect at the time of a partial load. <P>SOLUTION: Target supercharging pressure at the time of the partial load is computed higher in comparison with the time of a total load in driving to actuate only a primary turbo. Supercharging pressure PB at the time of the partial load is improved and in-cylinder intake air quantity at the time of the partial load is increased by making VN opening VNA at the time of the partial load to the closing side in comparison with the time of the total load so as to be the computed target supercharging pressure. The fuel consumption improving effect is obtained by making an air-fuel ratio at the time of the partial load lean. <P>COPYRIGHT: (C)2009,JPO&INPIT |
